TS-Optics 2" UCF Moon Filter, Planetary Filter and Nebula Filter

TS 2" UCF Moon, Planet and slight Nebula Filter

This filter is one of the best planetary filters we know. In the solar sytem the filter provides a significant increase in contrast, but the filter is even considerably more vesatile.

Due to slight suppresion of the blue light range, the UCF filter allows successfull observations and photographs in twilight or even at daytime. The contrast is increased and the blue sky background is reduced.

In addition, the UCF also increases the contrast of reddish gas nebulae, also called H-II regions. Observations of planetary nebulae also benefit from it. Overall the filter effect is not as strong as from a standard nebula filter, for example from a UHC. For this reason, the UCF is well suited also for smaller telescopes.

Replacement and supplement of colour filters

The TS UCF replaces many colour filter and it has an important advantage. The image is less coloured than with a mere colour filter, thus the natural impression of the moon or a planet is retained.

Due to the threads at both sides of the metal filter cell, the UCF can also be combined with other 2" colour filters or with a 2" neutral grey filter. This results in new interesting fields of application.
